Prove You Created It First
Timestamp your content before it gets stolen. Blockchain-anchored proof of creation.
Content Theft Is Rampant
You spend hours creating. Someone steals it in seconds. Without proof, you have no recourse.
Lost to Content Theft
Creators lose billions annually to unauthorized use of their work without proper attribution or payment.
Unresolved Disputes
Most creators abandon copyright claims because they can't prove they created the work first.
Training Without Consent
Your content is scraped to train AI models. Without proof of creation, you can't opt out.
How CertNode Protects Your Work
Create a cryptographic timestamp the moment you finish. Your proof remains independently verifiable.
One-Click Timestamping
Upload your file, get a cryptographic proof in seconds. Works with images, videos, audio, documents, code, and any digital file.
Bitcoin Blockchain Anchor
Your proof is anchored to the Bitcoin blockchain via OpenTimestamps. Immutable, decentralized, and permanent.
RFC 3161 Legal Standard
Legal-grade timestamps recognized by courts worldwide. The same standard used by banks and governments.
Shareable Verification Page
Get a public verification link anyone can check. Embed badges on your site. Prove ownership instantly.
Protect Your Work in 3 Steps
Upload Your Content
Drag and drop any file. We compute a SHA-256 hash (fingerprint) of your content. Your actual file never leaves your device if you prefer.
Get Your Timestamp
In seconds, we create a cryptographic proof with three layers of timestamps: CertNode signature, RFC 3161 legal timestamp, and Bitcoin blockchain anchor.
Share Your Proof
Get a public verification link and embeddable badge. Anyone can verify your proof without an account.

Someone was selling my artwork on Etsy. I sent them my CertNode proof showing I created it 6 months before they started selling. They took it down within 24 hours.
Common Questions
How is this different from posting on social media?
Social media timestamps can be manipulated and lack independent verification. CertNode uses RFC 3161 (the same standard used by banks and governments) and Bitcoin blockchain anchoring to create tamper-proof, independently verifiable proof.
Do you store my content?
No. We only store a cryptographic hash (fingerprint) of your content. Your actual files remain on your device. The hash proves the content existed without revealing what it is.
Will this hold up in court?
Yes. RFC 3161 timestamps are recognized as legal evidence in courts worldwide. Our proofs have been used successfully in copyright disputes, intellectual property cases, and contract disputes.
What if CertNode shuts down?
Your proofs are anchored to the Bitcoin blockchain, which is decentralized and permanent. Even if CertNode disappears, your timestamps remain independently verifiable on the public blockchain.
